Digital signal processor
M4DDM: This diversity delay monitor is the first Day Sequerra product to incorporate the company's newly developed digital signal processing (DSP) architecture. The M4DDM DSP runs the Day Sequerra Timelock algorithm to automatically maintain alignment of the HD Radio main program signal (MPS) analog and HD-1 digital audio. Using its selective off-air tuner, the M4DDM measures the MPS analog and HD-1 digital audio diversity and generates a continuous stream of correction vectors to keep the analog and digital audio time and level aligned. These correction vectors can be processed internally by the M4DDM to delay the digital program audio or can be sent via Ethernet to an HD Radio Embedded Exporter to provide the necessary delay. Additionally, the unit has digital audio outputs for confidence monitoring and alarm outputs for loss of program audio and OFDM sidebands as well as HD Radio data and RBDS data payloads. The algorithm used in the M4DDM is based on a new digital audio correlation methodology developed jointly by Harris and Day Sequerra.
